These are the tanks that the first and second players control. Player 1 controls the yellow tank, and player 2 controls the green tank simultaneously. Both tanks can only have one of their own shots on the screen at one time, and may not fire again until the shot hits an enemy or collides with a wall. Unless a force field is surrounding the tanks, preventing them from taking damage, they can be destroyed by one enemy bullet. If one player shoots another, it will prevent the other player from moving, although it will still be possible to turn and fire.

A power-up will spawn in one of 16 random locations on the screen whenever one of the three flashing tanks (which appear in each stage as the 4th, 11th, and 18th tank to spawn) is hit. They will disappear when another flashing tank spawns. Touching a power-up will collect it (it will then disappear) and you will earn 500 points as the power-up's effect is activated.

Grenade

Destroys every enemy currently on the screen.

No credit given for destroying the tanks wiped out by this powerup during the end-stage bonus points tally.

Helmet

Gives a temporary force field that shields from enemy shots, like the one at the beginning of every stage.

Shovel

Turns the brick walls around the fortress to stone, which gives temporary invulnerability to the walls, preventing enemies from destroying it.

Repairs all the damage previously done to the wall.

Star

Increases your offensive power by one tier (tiers are: default, second, third, and fourth). Power level only resets to default when you die.

First star (second tier): fired bullets are as fast as Power Tanks' bullets.

Second star (third tier): two bullets can be fired on the screen at a time.

Third star (fourth tier): fired bullets can destroy steel walls and are twice as effective against brick walls.
